The "do everything" tank - Surly LHT

If this was my bike I would do the following:

• Shimano Alfine Di2 group £455
  
• Shimano CX 77 disc brakes £125 the pair (I know a man who has a pair for sale BNIB)
  
• Shutter Precision disc hub front ~£100
  
• Mavic TN719 rims, double butted spokes
  
• Bang a 44T Thorn ring on that SRAM crankset
  
• Wallop.
